I've been researching some backlinks from a competitor of mine and came across something pretty strange. This is his sales page http://www.ticketluck.com/theater-tickets/Wicked/index.php Here are some of the sites that are linking in. http://loansmagician.com/ http://www.hrlady.com/partners.php http://www.cikm.org/ All of the sites linking in have what appears to be the original content on them, but then there is a ton of additional information that ticketluck has put on the site to make it blend right in with the original content. Some of these sites even have pagerank. My question is how is ticketluck obtaining these site with rank that already have content on them. What am I missing here. He's obviously doing something with these sites to boost his SEO, but I can't figure out how or what. Anyone have ideas of how to replicate what they are doing? They have some incredible rank in my niche.
